<Activation Process>

The procedure of an activation process at cellular phone 100 (first cellular phone 100A or second cellular phone 100B) according to the present embodiment will be described hereinafter. FIG. 11 is a flowchart of the procedure of an activation process at cellular phone 100 according to the present embodiment.

Referring to FIG. 11, upon the user carrying out a handwriting chat activation operation, control unit 110 of cellular phone 100 determines whether it is an application activation operation by a function embedded file (step S102). When not the activation operation of an application by the posting function embedded file (NO at step S102), control unit 110 determines whether the application is already in activation or not (step S104).

When the application is already in activation (YES at step S104), control unit 110 executes the process from step S122.

When the application is not yet activated (NO at step S104), control unit 110 initializes various data (step S106). For example, control unit 110 clears the memory region of the handwriting plane. For example, control unit 110 clears the memory region of the image plane. For example, control unit 110 sets or places the designation of a feature button corresponding to a defined value.

Control unit 110 sets the CM (chat mode) to 0 (non-chat) (step S108). Control unit 110 executes the process from step S122.

In an application activation operation by the posting function embedded file (YES at step S102), control unit 110 downloads the posting function embedded file from posting server 400 via communication device 101 (step S110). Specifically, control unit 110 sets various values to the system variables directed to posting. For example, control unit 110 stores in volatile memory 103 an underlying image (INITIMG), the designation of a posting feature button (BTNNAME), and the mail address of the post destination (SENDADR) as the system variables set by the posting function embedded file.

Control unit 110 initializes the variables related to the screen presented by the application (step S112). For example, control unit 110 clears the memory region of the handwriting plane. For example, control unit 110 writes INTIMG to the image plane. For example, control unit 110 sets or places the designation of a feature button to the value of BTNNAME.

Control unit 110 determines whether the application is already activated or not (step S114). When the application is not yet activated (NO at step S114), control unit 110 repeats the process from step S108.

When the application is already activated (YES at step S114), control unit 110 determines whether CM=1 or not (step S116). When not CM=1 (NO at step S116), control unit 110 repeats the process from step S122.

When CM=1 is established (YES at step S116), control unit 110 transmits the posting function embedded file to another terminal via communication device 101 (step S118). Control unit 110 transmits a clear operation of the handwriting plane and a drawing operation of the underlying image (INITIMG) as the posting function embedded operation to the relevant another terminal via communication device 101 (step S120).

Control unit 110 determines whether CM=1 is established or not (step S122). Specifically, control unit 110 determines whether currently engaged in a chat with another terminal. When cellular phone 100 is currently engaged in a chat with another terminal (YES at step S122), control unit 110 executes a chat process. The chat process will be described afterwards.

When cellular phone 100 is not currently engaged in a chat with another terminal (NO at step S122), control unit 110 executes a non-chat process (unitary usage process). The non-chat process will be described afterwards.
